Bvckup 2 does not handle per-monitor DPI scaling properly

Thought first of sending a bug report but perhaps a forum thread is better.

Bvckup 2 does not seem to handle per-monitor DPI scaling properly on Windows 10 v1903. Instead it will always use the 150% DPI scaling set on my primary display and use that scaling even on my secondary monitor to the left. This have, to my knowledge, always been the case, and is not a new issue.

All High DPI scaling override compatibility modes of Windows have been tested:

[no override] - Bvckup 2 uses the 150% DPI scaling on both monitors.

[Application] - Bvckup 2 uses the 150% DPI scaling on both monitors.

[System] - The application displays correctly at 100% scaling on the 2560x1440 monitor, but fuzzy (this is basically the norm of this mode) when scaled to 150% DPI on the 3840x2160 monitor.

[System (Enhanced)] - The application displays correctly at 100% scaling on the 2560x1440 monitor, but slightly less fuzzy (this is also basically the norm of this mode) when scaled to 150% DPI on the 3840x2160 monitor.

Here's a few screenshots with High DPI scaling overrides disabled, with File Explorer for scale:

Support for dynamic DPI scaling has been on the ToDo list for ages (you are 100% right there), but at the very bottom of it. This is because it requires a LOT of work *and* there's virtually no demand for it.

It also doesn't help, I guess, that I personally really don't like the aesthetics of multi-monitor setups where monitors are scaled differently.

So, yes, it's a known issue, which will be resolved at some point, but I cannot give you an ETA for it.
